Final answer:
Motorist service signs provide information about facilities or services available for drivers.
Step-by-step explanation:
Motorist service signs are road signs that provide information about facilities or services available for drivers. These signs are typically blue with white pictograms and text. For example, a motorist service sign may have a pictogram of a gas pump and the word 'GAS' to indicate the presence of a gas station nearby. Other common motorist service signs include those for rest areas, food, lodging, hospitals, and attractions.
These signs help drivers make informed decisions while on the road by alerting them to the availability of services they may need, such as fuel, restrooms, or food. It is important for drivers to pay attention to these signs and follow them to ensure their safety and convenience.
